Total number of virtual routers : 1 Interface Vlan-interface2 VRID : 1 Adver Timer : 100 Admin Status : Up State : Master Config Pri : 100 Running Pri : 100 Preempt Mode : Yes Delay Time : 5 Auth Type : None Virtual IP : FE80::10 1::10 Virtual MAC : 0000-5e00-0201 Master IP : FE80::2 The output shows that when Switch A fails, Switch B takes over to forward packets from Host A to Host B. # Recover the link between Host A and Switch A, and display detailed information about VRRP group 1 on Switch A. [SwitchA-Vlan-interface2] display vrrp ipv6 verbose IPv6 Virtual Router Information: Running Mode : Standard Total number of virtual routers : 1 Interface Vlan-interface2 VRID : 1 Adver Timer : 100 Admin Status : Up State : Master Config Pri : 110 Running Pri : 110 Preempt Mode : Yes Delay Time : 5 Auth Type : None Virtual IP : FE80::10 1::10 Virtual MAC : 0000-5e00-0201 Master IP : FE80::1 The output shows that after Switch A resumes normal operation, it becomes the master to forward packets from Host A to Host B. Multiple VRRP groups configuration example This section provides an example of configuring multiple VRRP groups on switches. Network requirements Switch A and Switch B form two VRRP groups. VRRP group 1 uses the virtual IPv6 addresses 1::10/64 and FE80::10 to provide gateway service for hosts in VLAN 2, and VRRP group 2 uses the virtual IPv6 addresses 2::10/64 and FE90::10 to provide gateway service for hosts in VLAN 3, as shown in Figure 24. Hosts in VLAN 2 learn 1::10/64 as their default gateway, and hosts in VLAN 3 learn 2::10/64 as their default gateway from RA messages sent by the switches. Assign Switch A a higher priority than Switch B in VRRP group 1 but a lower priority in VRRP group 2 to distribute the traffic from VLAN 2 and VLAN 3 between the two switches. When one of the switches fails, the healthy switch provides gateway service for both VLANs. 75
